The quenching lamp [A], an array of LEDs, is behind the LPH [B].
After the drum [A] is cleaned by the cleaning blade, light from the quenching lamp
removes unwanted charge on the drum. This prepares the drum for the subsequent
copy cycle.
The quenching lamp switches on and off with the drum motor (the lamp stays on
while the OPC drum turns).
